Description: his example calculates the impedance of a microstrip line on a printed circuit board. It compares the impedance with that obtained from an analytical formula given the dimensions of the micro strip and permittivity of the circuit board. This formula is available as a script with the following arguments: width, height, height of conductor, and permittivity of circuit board. Platform: |

Description: Microstrip junctions are most widely used building elements of
microwave integrated circuits. Serve to connect microstrip devices, divide, or combine
power, those elements represent simple microstrip discontinuities characterized by
appropriate scattering matrices. Based on the knowledge of frequency-dependent
parameters of circuit elements and junctions connecting these elements, large microwave
devices can be easily analyzed by the circuit theory. That is why the accurate modeling
basic microstrip junctions in terms of S matrix elements is a problem of great
importance for modern microwave CAD. Platform: |

Description: Microstrip is a type of electrical transmission line which can be fabricated using printed circuit board technology, and is used to convey microwave-frequency signals. It consists of a conducting strip separated from a ground plane by a dielectric layer known as the substrate. Microwave components such as antennas, couplers, filters, power dividers etc. can be formed from microstrip, the entire device existing as the pattern of metallization on the substrate. Microstrip is thus much less expensive than traditional waveguide technology, as well as being far lighter and more compact. Microstrip was developed by ITT laboratories as a competitor to stripline (first published by Grieg and Engelmann in the December 1952 IRE proceedings). Platform: |

Description: 射频（RF）工程是电气工程的一个子集，处理设备，被设计为工作在“无线电频谱。这些器件工作在约3千赫至300赫兹的范围内。
几乎所有的发送或接收无线电波，其中包括，但不限于，手机，对讲机，无线网络和双向无线电射频工程纳入。
RF工程是一个高度专业化的领域，通常在两个领域之一 1）提供或控制某种覆盖天线/传输系统和2）生成或接收信号或从该传输系统等通讯电子设备或控件。要生产质量效果，深入了解数学，物理，通用电子理论以及在波的传播，阻抗变换，滤波器，微带电路板设计等领域的专门培训，可能是必需的。由于射频同时进行，通过典型的导体，以及通过空间的许多方法，初步设计RF电路通常承担最终的优化物理电路非常的相似性很小。倘的设计往往是必需的，以实现预期的结果。-Radio frequency (RF) engineering is a subset of electrical engineering that deals with devices that are designed to operate in the Radio Frequency spectrum. These devices operate within the range of about 3 kHz up to 300 GHz.
RF engineering is incorporated into almost everything that transmits or receives a radio wave, which includes, but is not limited to, Mobile Phones, Radios, WiFi, and two-way radios.
RF engineering is a highly specialized field falling typically in one of two areas 1) providing or controlling coverage with some kind of antenna/transmission system and 2) generating or receiving signals to or from that transmission system to other communications electronics or controls. To produce quality results, an in-depth knowledge of mathematics, physics, general electronics theory as well as specialized training in areas such as wave propagation, impedance transformations, filters, microstrip circuit board design, etc. may be required.
